2026-02-06dmaengine: ti: k3-udma: fix device leak on udma lookupJohan Hovold1-1/+1
commit 430f7803b69cd5e5694e5dfc884c6628870af36e upstream. Make sure to drop the reference taken when looking up the UDMA platform device. Note that holding a reference to a platform device does not prevent its driver data from going away so there is no point in keeping the reference after the lookup helper returns.

2025-09-19dmaengine: ti: edma: Fix memory allocation size for queue_priority_mapAnders Roxell1-2/+2
[ Upstream commit e63419dbf2ceb083c1651852209c7f048089ac0f ] Fix a critical memory allocation bug in edma_setup_from_hw() where queue_priority_map was allocated with insufficient memory. The code declared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8), but allocated memory using sizeof(s8) instead of the correct size. This caused out-of-bounds memory writes when accessing: queue_priority_map[i][0] = i; queue_priority_map[i][1] = i; The bug manifested as kernel crashes with "Oops - undefined instruction" on ARM platforms (BeagleBoard-X15) during EDMA driver probe, as the memory corruption triggered kernel hardening features on Clang. Change the allocation to use sizeof(*queue_priority_map) which automatically gets the correct size for the 2D array structure.

2025-05-22dmaengine: ti: k3-udma: Use cap_mask directly from dma_device structure ↵Yemike Abhilash Chandra1-2/+1
instead of a local copy commit 8ca9590c39b69b55a8de63d2b21b0d44f523b43a upstream. Currently, a local dma_cap_mask_t variable is used to store device cap_mask within udma_of_xlate(). However, the DMA_PRIVATE flag in the device cap_mask can get cleared when the last channel is released. This can happen right after storing the cap_mask locally in udma_of_xlate(), and subsequent dma_request_channel() can fail due to mismatch in the cap_mask. Fix this by removing the local dma_cap_mask_t variable and directly using the one from the dma_device structure.

2022-09-05dmaengine: ti: k3-udma: Reset UDMA_CHAN_RT byte counters to prevent overflowVaishnav Achath1-8/+17
UDMA_CHAN_RT_*BCNT_REG stores the real-time channel bytecount statistics. These registers are 32-bit hardware counters and the driver uses these counters to monitor the operational progress status for a channel, when transferring more than 4GB of data it was observed that these counters overflow and completion calculation of a operation gets affected and the transfer hangs indefinitely. This commit adds changes to decrease the byte count for every complete transaction so that these registers never overflow and the proper byte count statistics is maintained for ongoing transaction by the RT counters. Earlier uc->bcnt used to maintain a count of the completed bytes at driver side, since the RT counters maintain the statistics of current transaction now, the maintenance of uc->bcnt is not necessary.

2021-05-31dmaengine: ti: omap-dma: Skip pointless cpu_pm context restore on errorsTony Lindgren1-1/+2
There's no need to restore DMA context on CPU_CLUSTER_PM_ENTER_FAILED as the DMA context won't be lost on errors. Note that this does not cause invalid context restore as we already check for busy DMA with omap_dma_busy() in CPU_CLUSTER_PM_ENTER, and block any deeper idle states for the SoC by returning NOTIFY_BAD if busy. If other drivers block deeper idle states with cpu_pm, we now just do a pointless restore, but only if dma was not busy on CPU_CLUSTER_PM_ENTER. Let's update the CPU_CLUSTER_PM_ENTER_FAILED handling for correctness, and add a comment.
